Bluely

Inspiration

We kept seeing people build iMessage bots—Jarvis-style assistants, AI agents, feedback collectors—but every setup was custom, messy, and not reusable. So we built Bluely: a plug-and-play iMessage bot framework focused on real-world utility, with AI-first integrations baked in.

What it does

Bluely is a Python SDK and framework that makes it dead simple to build iMessage bots. It abstracts away BlueBubbles' iMessage plumbing and gives devs a clean interface—like building Slack or Discord bots, but for iMessage. Our flagship bot helps early-stage founders automatically collect user feedback over iMessage, summarize it using AI, and triage it into actionable Linear issues.

How we built it

We used the BlueBubbles API to tap into iMessage, and built a Pythonic SDK on top with routing, message handling, and response templates. Then we integrated OpenAI for summarization and Linear’s API for issue creation. We built five bots using Bluely, including a therapy bot, a scheduling assistant, and a fact-checking agent—but our founder feedback bot is the one we’re most excited about.

Challenges we ran into

Apple doesn’t expose iMessage APIs, so getting stable and real-time access requires reverse engineering via BlueBubbles. Making the SDK general enough to support different bot types—but still easy to use—was a tricky balance. Integrating AI without losing control over hallucinations also required tuning.

Accomplishments that we're proud of

Our flagship founder bot works. It receives iMessage feedback from users, uses GPT to summarize and categorize it, and files it directly to Linear with context. In less than 24 hours, we built multiple bots using Bluely—each one showcasing a different vertical—but this one made real product feedback effortless.

What we learned

iMessage is wildly underutilized in product workflows. The response rates are better, the UX is friendlier, and it’s where users already are. Founders shouldn’t have to forward texts, open Notion, or guess what users want—our bot handles all that with AI.

What's next for Bluely

We’re open-sourcing Bluely with docs and templates for rapid bot building. We’ll expand integrations—Notion, Slack, Calendly, Supabase—and focus on AI-first bots that solve real pain points. The founder feedback bot is just the beginning. We want to power every conversational use case on the most engaging messaging platform in the world.
